Three types of aluminum alloys can be considered for this application --

• a 206 aluminum alloy with a T7 heat treat

• a B356 aluminum alloy with a T6 heat treat

• a 535 aluminum alloy with no heat treat

Which aluminum alloy would you choose for the brake pedal, based on strength, ductility, corrosion resistance and castability requirements, as shown below?

Corrosion Resistance
(1= Excellent, 5= Poor)

Hot Tear Resistance
(1= Excellent, 5= Poor)
